Poor workmanship and disrespecting customer appointments

Contacted Andrew from Mend A Bath in Johannesburg concerning a 10cm crack issue on my jacuzzi. Unfortunately, he encountered difficulties in adhering to the initially scheduled appointment, causing significant delays. Notably, he did not make the effort to communicate his inability to make the initial appointment. Upon eventual arrival, he proceeded to fix and respray the crack. However, disappointingly, the crack reappeared just two days later. It became evident that Andrew lacked proper communication etiquette and showed a disregard for customer appointments. Despite my attempts to address the issue, a refund was requested, and to date, it has not been received, leaving the crack unresolved.
